Wood-saw



A UNITED sTATEs PATENT OEEICE.

WOOD-SAW.

Specification of Letters Patent-.Nd 10,439, dated January 24, 1854.

To all whom t may concern:

Be it known that we, ROMEO ANDREWS and' make and use our invention we will proceed to describe the same.

Ve take a saw plate of the customary make, and cut and form the teeth in the manner or nearlyiso as shown in the plan. One portion of the teeth are cut in the usual manner for sawing, and the other portion are out and formed as marked letters, A, on the plan, having the appearance as if they were cut backward. These are the planing teeth and have asharp chisel shaped edge. It is the peculiar form of these teeth that gives the merit to this invention. Instead of being set in the usual way, we curve them sidewise a small portion beyond the thickness of the plate and the thickness of a shaving beyond the set of the sawing tooth preceding. The curve of the tooth commences well down into the plate and gently curves outward up to the point which is turned inward just so as to clear the point of theV can be used in large work kfor board sawing or other work, giving a`beautiful smooth face to the same and requiring no planing afterward.

vWhat we claim as our invention and desire to secure by Letters Patent is- The peculiar form and relative position ofr the planing teeth in combinationy with the sawing teeth, substantially as herein de' scribed and for the purpose herein set forth..
